I still feel the point of this is he is married, and should be faithful. He is lying, he is emotionally cheating and she should not be made to feel she should put up with it. I honestly believe that being trans does NOT excuse this type of behavior. Many make make excuses for it, but it is NOT appropriate.
He should ask for a divorce, if he cannot remain faithful....I say this because I was in a marriage for 16 years, and finally came out as Gay. I did not cheat, I did not lie, I handled it like an adult should and asked for a divorce. I NEEDED to be me. My mate wanted to stay married and have an open marriage which we both agreed to and tried for a bit, we did end up divorced however in the end. I fell in love with a woman(who is NB by the way) and ended up leaving for them. They are now undergoing top surgery.(yay!) I really get tired of excuses afforded those who are trans or gay. Yeah, we have to be who we are, but ya know what? Our struggle does NOT give us the right to destroy others because "we are in search of ourselves". Period.
